Computed tomography angiography of whole aorta was performed.
Intimal flap was identified from aortic valvolar plane to external iliac arteries, with true lumen and false lumen equally opacified by contrast medium in arterial phase.
Small haematoma surrounding thoracic ascending aorta was seen.
Epiaortic arteries wasn't involed; celiac trunk, superior mesentery artery originate from true lumen.
Right renal artery originates from true lumen and it is involved by intimal flap in its proximal tract, with normal renal perfusion.
Left renal artery originates from false lumen with left renal hypoperfusion.
